Russian President Dmitry Medvedev tweaked Mitt Romney for his characterization of Russia as the "No. 1 geopolitical foe" of the United States, saying the comments did not reflect the current relationship between the two countries, Gabriella Schwartz reports on CNN's Political Ticker.

"It is very reminiscent of Hollywood and also of a certain phase in Russian-U.S. relations," Medvedev said at the end of the nuclear security summit in South Korea Tuesday.

(CNN) – Mitt Romney should be in Washington, D.C. while the Supreme Court hears a challenge to the national health care law, Rick Santorum said Monday.

"Mitt Romney's 3,000 miles away. He should be here," the Republican presidential candidate said in an interview set to air on CNN's "The Situation Room." "He doesn't want to talk about the issue because he can't on substance disagree with the policies of this administration."

(CNN) – Newt Gingrich may be far behind in the GOP delegate count – he has a quarter of the number frontrunner Mitt Romney does – but said on CNN's "The Situation Room with Wolf Blitzer" that he isn't bowing out of the race.

"I think this is not over until it's over and obviously, if he does become the nominee, I will support him," the former House speaker said of Romney, calling him "the weakest front runner in modern times."

"I'm not going to worry too much about what Rick is saying these days," Romney said on CNN's "The Situation Room with Wolf Blitzer." "I know when you're falling further and further behind, you get a little more animated."
